Airway opening assisting device

Abstract

The invention discloses an airway opening aid, comprising a base, a threaded hole is arranged on the base, a fixing block is symmetrically mounted on both ends of the top of the base, a through hole is opened on the fixing block, and the fixing block is fixed on the base by screws Above, the fixing block is provided with a first support rod and a support plate, the first support rod is located on the side close to the screw, the top end of the first support rod is connected with a positioning pin at one end of the second support rod, and the other end of the second support rod The supporting device is connected with the positioning pin. The beneficial effects of the present invention are as follows: the structure is simple, the manpower is reduced, the head of the injured person is fixed by the support plate and the fixing block, the head of the person is prevented from shaking, and the first support rod, the second support rod and the support device are used to prevent the injured person from shaking. The chin acts as a support and fixation to prevent airway obstruction caused by the tongue falling back and endanger the life of the wounded. At the same time, the chin support angle is adjusted through the support head, spring and sleeve rod, and the fixed width is adjusted through the base, fixing block and screw to adapt to different injured.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an airway opening assist device. Background technique [0002] Airway opening is a very common emergency rescue technique, which can be used for emergency airway opening during cardiopulmonary resuscitation or emergency airway establishment for patients with airway obstruction caused by tongue falling back due to various reasons, so as to ensure Patient has adequate ventilation and oxygen supply. [0003] For patients who need to keep the airway unobstructed for a long time and cannot establish an airway such as tracheal intubation or tracheotomy in a short period of time, the method of supporting the mandible with both hands is often used clinically. Keep the sniffing position (or "nose sniffing position"). At this time, the three axes of the patient's mouth and throat overlap, which is most conducive to the patient's ventilation. [0004] Among the people who die from emerge...

AI Technical Summary

Problems solved by technology

However, the problems commonly encountered at present are: 1. People without formal training are difficult to achieve effective mandibular support at all, causing the obstruction to be unable to be removed and missing the golden time for rescue; The mandible will also be unable to keep the mandible held up effectively due to hand soreness, which will lead to (1) a decrease in blood oxygen saturation; (2) a large amount of gas is blown into the stomach during artificial oxygenation, increasing the risk of vomiting and aspiration , which greatly increases the risk of anesthesia; 3. In general anesthesia, after the patient has been injected with general anesthetic, the base of the tongue falls back and stops breathing. Weak hand strength will inevitably lead to poor lifting effect, especially for obese people, so oxygen cannot be given effectively. Due to poor mandibular lifting, the pressurized oxygen supply of the mask failed to improve the patient's oxygen reserve, resulting in insufficient time for intubation. Various complications are prone to occur; 4. For intravenous anesthesia for minor operations without intubation: (1) due to fear of prolonged respira
